The Brewers are 60-59 -- third in the National League Central and two games behind division leader Chicago. Milwaukee's second-base contingent, which consists primarily of Jonathan Villar and Eric Sogard, ranks last in the league with a .672 OPS.

The Brewers had expressed interest in Ian Kinsler of the Detroit Tigers, before shifting their attention to Walker since the July 31 non-waiver trade deadline. Walker became eligible to be traded to any team after recently clearing waivers.

Walker, 31, hit .264 with 10 home runs and 36 RBIs in 73 games with New York this season.

He has a career .272/.339/.437 slash line over nine seasons with the Pirates and the Mets. New York acquired Walker from Pittsburgh in a trade for pitcher Jon Niese in December 2015.

Eric Sogard scampered home with the winning run on a wild pitch in the bottom of the 10th inning and the Milwaukee Brewers snapped a six-game losing streak with a 6-5 victory over the Cincinnati Reds on Saturday night.

"He's a first-rate guy,'' Mets general manager Sandy Alderson said of Walker. "He was very important in the clubhouse, and we're very glad we had him for the time that we did. I think he distinguished himself in his time as a Met.''

Walker was taking batting practice with his New York teammates two hours before Saturday's game Mets-Phillies game at Citizens Bank Park when Alderson came out and conferred with manager Terry Collins behind the batting cage. A few minutes later, Walker and Alderson left the field for the clubhouse.

Walker was replaced by Jose Reyes at second base 10 minutes before the start of the game. Walker declined comment before leaving the park on a golf cart in the sixth inning.

The Mets are a disappointing 52-62 and third in the NL East, and they've recently begun selling off veteran pieces. They traded closer Addison Reed to the Boston Red Sox and sent first baseman Lucas Duda to the Tampa Bay Rays before the July 31 non-waiver trade deadline, and they shipped outfielder Jay Bruce to the Cleveland Indians for minor league pitcher Ryder Ryan on Wednesday.

Walker is signed to a one-year, $17.2 million contract and will be a free agent in November. The Mets are giving an undisclosed amount of cash to Milwaukee to help defray the $4.7 million that Walker is owed for the rest of this season.

Alderson said that Wilmer Flores and Reyes are likely to see the bulk of the playing time at second base after Walker's departure. And he indicated that Gavin Cecchini and Matt Reynolds also could work their way into the teams' second-base mix.

Alderson declined to speculate on whether the Mets expect any additional moves this month. Outfielder Curtis Granderson and infielder Asdrubal Cabrera have been mentioned as potential trade candidates.

"We still have inventory,'' Alderson said.

The New York Yankees were reportedly close to acquiring Walker in a trade before the deadline, only to back out because of concerns over Walker's medical reports.

Walker underwent season-ending back surgery in September, and he missed 36 games this year with a partially torn hamstring, but he told reporters this week that his health is not a concern.
